UNIIVERSAL ADJUSTER FOR PRINTING-FILMS.

Specification of Letters Patent.

Patented April 3, 1906.

Application filed August 18, 1904. Serial No. 221,240.

To aZZ whom it may concern:

Be it known that I, BENJAMIN DAY, a citizen of the United States, and aresident of West Hoboken, in the county of Hudson and State of NewJersey, have invented a new and Improved Universal Adjuster forPrinting-Films, of which the following is a full, clear, and exactdescription.

My invention relates to the manipulation of printing-films, one of whichis inclosed in an appropriate frame, my more particular object bein tosecure precision in the handling of the lm relatively to the work.

My invention further relates to certain means for adjusting the frame soas to bring it to a predetermined part of the work and for turning theframe and the work to different angles relatively to each other for thepurpose of producing various changes in shad- 11'1 lteference is to behad to the accompanying drawings, forming a part of this specification,in which similar characters of reference indicate corresponding parts inall the figures.

Figure 1 is a plan view showing the universal adjuster as mounted upon atable and i Fig. 2 is a vertical section ready for use. through the sameupon the lines 2 2 of Figs. 1 and 3. Fig. 3 is a rear elevation showingthe mechanism viewed as from the left of Fig. 1. Fig. 4 is an enlargeddetail in section upon the line 4 4 of Fig. 1 looking in the directionof the arrow. Fig. 5 is an enlarged detail section upon the line 5 5 ofFig. 1 looking in the direction of the arrow. Fig. 6 is a fragmentarysection upon the line 6 6 of Fig. 1 looking in the direction of thearrow. Fig. 7 is a vertical section upon the line 7 7 of Fig. 1 lookingin the direction of the arrow. Fig. 8 is a fragmentary horizontalsection upon the line 8 8 of Fig. 3 looking in the direction of thearrow. Fig. 9 is a perspective view of the weight used for steadying theapparatus relatively to the work. Fig. 10 1s a fragmentary plan viewshowing the apparatus used in connection with a revoluble board. Fig. 11is a fragmentary side elevation of the,

revoluble board, certain parts being broken away for the sake ofclearness and Fig. 12 is a fanciful v iew showing a specimen of the workdone by the mechanism.

A table is shown at 1.3 and is provided with Mounted upon this block, orother member and upon the upper surface of which the work is to be done.

' ers 20, provided with bearings 22 for engaging a revolublespring-pressed member 21, the purpose of which is to adjust the slide23, upon which the split bearing 24 is integrally mounted. Anadjusting-screw 25 is used for the purpose of moving one of thecentering-pins 19 relatively to the other. Thumbscrews 26 are revolublymounted in spacingblocks 27, movable on a rod 28 and carrying thecentering-pins 19 and their several devices for adjusting the same. Asthe sp,acing-blocks 27 and the parts accompanying the same are fullydescribed in my Patent No. 666,087 for Safety adjuster forprintingfilms, no detail description of the same is necessary in thepresent application. By loosening the screws 26 the spacing-blocks 27may be moved along the rod 28 to any desired point, so that the mountingof the printing-frame 17 upon the centering-pins 11:? is comparativelyeasy, as will be seen from Rigidly mounted upon each spacing-block 27 isa substantially V-shaped frame 27, in which the bearing 24 is free tomove when actuated by a screw 29. Each spacing-block 27 is provided witha friction-block 30, Fig. 4, which is clamped upon the rod 28 bypressure of the screw 26. A leaf-spring 31, connected with thespacing-blocks 27, normally supports the friction-block 30 out ofengagment with the rod 28. Each s acing-block 27 is further providedwith earings 32, which loosely encircle the rod 28 and are tightenedagainst the same when the screw 26 is rotated in the proper direction.The rod 28 is rigidly supported upon stub-arms 33 and clamped thereto bymeans of screws 34. The stub-arms are rigidly mounted upon a bar 35,provided. with a comparatively sharp bearing edge 36 (see Fig. 6) andare encircled by heads 39, integral with opposite ends of abearing-plate 37. This plate is strengthened by means of a rib 38,preferably integral therewith. Thumb-screws 41 are revolubly mounted inthe heads 39 and engage the bar 35, so as to clamp the same firmly inany position desired relatively to its lengththat is to say, the rod maybe slid endwise within any desired degree, and thus clamp ed in 'iWOplaces by the screws 41. The heads 39 are rigidly connected with theends of rods 40, which slidably engage heads 42, as shown moreparticularly in Fig. 5. Each head 42 is provided with end bearings 43and with a central bearing 44, the latter being provided with athumb-screw 45, which clamps the rod 40 at a point centrally of the head42. By this arrangement each head 42 presses upward against the lowerside of the rod 40, so as to bind the same firmly at three different Ipoints. Interposed between the rod 35 and the screw 41 for clamping thesame is a leafspring 46, attached tothe bearing-plate 37 and projectingwithin the head 39, so as to have the screw 41 force the spring directlyinto engagement with the rod 35, as will be understood from Figs. 6 and7. The heads 42 are rigidly mounted upon the outer ends of aconnecting-plate 41 and are preferably integral therewith. Securedrigidly to the connecting-plate 41" are rods 47, which slidably engageheads 48, provided with screws 49 and being similar in construction tothe heads 42. (Shown more particularly in Fig. 5'.) A revoluble plate 50supports the heads 48, so'that the rods 47 and all the parts connectedtherewith may be turned to different angles. A vertical supporting-plate51 is provided with a clamping-screw 52 for securing thesupporting-plate 51 against the bearing-plate 37 at any desired heightrelatively thereto, as will be seen from'Fig. 2. For this purpose thesupporting-plate 51 is provided with a slot 54, engaged by the screw 52.The bottom of the supporting-plate 51 is provided with feet 55 and withbraces 56 for the feet. These feet rest upon the table 13 or anyanaloous surface. A board 57 is provided, with tailpieces 58 rigidlysecured thereto, as will be seen from Fig. 1. A plate 59 is mounted uponthe board 57 and is provided with an indicating-mark 60. A clamp 61engages the revoluble plate 50 and may be pressed downward upon the sameby means of a knob 62, revolubly mounted upon a threaded screw 63". Therevoluble plate 50 is provided with a graduated scale 63 and, togetherwith the plate 59, having the indicating-mark 60, constitutes aprotractor for determining the angle assumed by the printing-frame 17with reference to the screw 63 as the center. A slide 64 is mountedwithin a slid'eway 64 and is provided with braces 64' integraltherewith. Braces 65 support the board 57 relatively to the slide 64, sothat when the slide moves upward or downward the board 57 is raised orlowered, as the case may be. The slide 64 is provided with a slot 66 andisheld in place by a clamping-knob 68, which forces the slide againstthe clamping member 67, as will be understood from Fig. 2. The slideway64" is rigidly mounted upon a vertical board 69. Clamping-plates 70 arerigidly mounted upon this board and engage the'top surface of the table13. Mounted rigidly upon the lower end of the board 69 is a bracket 71",provided with bearings 71 71 integrally connected therewith. Thisbracket is secured by means of fastenings 72 to the board 69. A slidingstem 73 is provided at its upper end with a clamping-block 74, whichengages the under side of the table 13. The sliding stem 73 is guided bya screw 7 3?, which engages a slot 7 3 The vertical stem 73 is threadedat its lower end, but does not revolve. It is engaged by a revolubleknob 75, provided internally, as shown, and held against verticalmovement by means of a fixed collar 76, connected rigidly with thebearing 71.

The apparatus as a whole is mounted upon the table 13 by placing theclamping-plates 70 above'the same and the clamping-block 74 below andturning the knob 75, so as to clamp the edge of the table firmly betweenthese parts, as indicated in Fig. 2. The knob 68 is next loosened andthe board 57 raised to any desired height commensurate with the heightof the block or other piece of work 15, and the knob 68 is againtightened, so as to clamp the slide 64 rigidly in position. The knob 62is now loosened and the protractor turned so that the film 16 rests uponthe work 15 at the desired angle. The supporting-plate rods 40 by meansof the screw 52'. All of these parts being in position, theprinting-film 16 now rests flatly upon the work 15. The frame 17 may beraised upon the centeringpins 19 and lowered so as to assume exactly thesame position that it had at first. The film is now raised and thenpressed downward upon the Work in the usual manner, whereupon pressureis applied to the upper side of the film and the impression made uponthe work. A weight 56*, provided with a handle 56*, is employed to holdthe parts steady'with'reference to the work. If now it be desired toturn the film to a diflerent angle relatively to the work'15, theprotractor is used and the apparatus adjusted, whereupon anotherimpression may be superimposed upon the first, so that the designprinted upon the work will be composite in its nature, substantially asshown in Fig. 12. It will be noted that by virtue of the severaladjustments above described the printingframe 17 can be brought to anydesired height relatively to the work or to any desired distance fromthe edge of the table by sliding the extension-rods 4O 47 and may becaused to move radially by means of the sliding bar '35. It will also benoted that as the spacing-blocks 27 are slidable upon the rod 28 theprinting-frame may be given a still greater lateral amplitude ofadjustment. The result is that the printing-frame 17 can be adjusted in"an infinite variety of ways.

In Figs. 10 and 11 instead of using the ta- 51 is also adjustedrelatively to the IIO Biases ble 13 (shown in Fig. 1) I use a table 76,centrally mounted upon which is a revoluble board 77, free to turn upona pivot 78 and provided with fixed bars 79, which space the revolubleboard from the table 76. A clamp 80 is actuated by means of a nut 81,revolubly mounted upon a screw 82, which is fixed firmly to the clampand movable therewith in the general direction of the axis of the screw.The clamp 80 is provided with an indicating-mark 83, which may bebrought into registry with a radial line 82 upon the revoluble board.The board is also provided with concentric circles 82 for the purpose ofaiding the positioning of the work.

By the use of the table 76 and the revoluble board 77 (shown in Figs. 10and 11) a still further range of adaptability is given to the apparatusabove described. Instead of moving the printing-frame 17 by means of theprotractor the revoluble board 77 may be turned by hand and held by thescrew 81, so as to bring the work whichrests upon the revoluble board 77to any desired angle relatively to the printing-frame 16.

In Fig. 12 is shown a specimen of the work done by the apparatus abovedescribed. At 12 is shown a simple tint printed by the film upon paperfrom a stipple design. At 12 is shown a print made from the same design,but superimposed upon itself at a different angle. At 12 and 12 areshown other impressions taken from the same design, the only differencebeing the variation of the angle at which the design is superimposedupon itself.

The angles to which the revoluble board is V turned may be noted and arecord kept of the same, so that the same result in superimposing astipple tint on itself may be repeated at any future time. The slightestvariation from this angle changes the character of the combination of astipple tint with itself. Tints superimposed on each other form printedcombination, the charecter of which can only be reproduced when theselected angles at which they were printed one on the other is known tothe operator. Hence one operator might print a combination that it wouldbe nnpossible for another operator to copy unless he knew the angles atwhich the first operator set the revoluble board when printing a stippletint on top of a first impression of itself.

As may be seen from Fig. 10, the movements of the revoluble board are tosome extent independent of the movements of the printing-film frame. Theresult is that the printing-film may be adjusted to different anglesrelatively to the center of the protractor, whereas by movements of therevoluble board the stone or other work may be turned to differentangles relatively to the center of the board. This renders almostinfinite the number of combinations and permutations for which theinstruments may be used-that is to say, the number of composite designswhich may be produced by the joint action of the rotation of therevoluble board to different angles and the turning of the protractor todifferent angles'is multiplied infinitely by the conjoint use of therevoluble board and the protractor.
